Access Point #: SC.3.P.9.In.1

Describe changes in the state of water as a result of freezing and melting.
General Information
Number: SC.3.P.9.In.1
Category: Independent
Date Adopted or Revised: 02/08
Big Idea: Changes in Matter : A. Matter can undergo a variety of changes.

B. Matter can be changed physically or chemically.

Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A and B.

Clarification for Grades 6-8: The target understanding for students in the middle grades should begin to transition the focus to: C. When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

Lesson Plan

States of Water- Part 1:

Students will be able to describe water as it changes states through melting and freezing.

Type: Lesson Plan


Water Phases:

Water is ubiquitous on Earth, but is quite a unique substance because it easily exists in all three of its forms (liquid, ice, vapor) on Earth, unlike the other substances that can exist in these three phases. This slideshow depicts water in each of its three phases.

Type: Presentation/Slideshow

Unit/Lesson Sequence

States of Matter | Inquiry in Action:

In the first activity of this unit, students consider how heating and cooling affect molecular motion. The subsequent activities extend this idea to explore the relationship between temperature and the state changes of water. After considering their own experiences with evaporation and condensation, students discover that adding heat to water increases the rate of evaporation and cooling water vapor increases the rate of condensation. Students then investigate what causes moisture to form on the outside of a cold cup. As an extension, students see that at even lower temperatures water vapor can condense on the outside of a container and then freeze to form ice.
